EYEGLASS-MOUNTING.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed January 17, 1910. Serial No. 538,380.

T 0 all whom it may concern:

Be it known that 1, Leo F. An'r, of the city of Albany, in the county of Albany and State of New York, have invented certain .new and useful Improvements in EyeglasslVIountings; and I do hereby declare the following to be a full, clear, and exact description of the same. reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

The present invention relates to eyeglass mountings of the type in which the guards are moved toward the nose by springs or other resilient means and are separated by manually operable portions, such for instance as finger pieces arranged at the front of the mounting; and an object of the invention is to provide a construction in which the lens attaching devices are separate from the bridging portion, the parts being so constructed and arranged that a very small pupillary distance may be obtained.

Another object of the invention is to pro vide a mounting of the above type which will permit the inset and the outset of the lenses.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is an enlarged front view of a mounting constructed in accordance with the present improvements, a portion thereof being shown in vertical section; Fig. 2 is a detail view showing the top of the same mounting in proximity to one of the guards; Fig. 3 is a detail view showing the bottom of the same mounting in proximity to one of the guards, the nose bearing member of the guard being shown in section; Fig. 4 is a central transverse sectional view of the mounting; Fig. 5 is a section on the line a-a of Fig. 2; Figs. 6 and 6* are respectively detail views of a lens attaching device and an end of the bridging portion; Fig. 7 is a detail view showing the top of another mounting constructed in accordance with this invention in proximity to one of the guards; Fig. 8 is a central vertical section of this latter embodiment; Figs. 9 and 9 are respectively a detail view of one of the lens attaching devices, shown in Figs. 7 and 8, and a detail view of one end of the bridging portion of the same figures; Fig. 10 is a detail view of still another embodiment of the invention, and Fig. 11 is a section on the line 0-5 of Fig. 10.

In the embodiment of the invention shown in Figs. 1 to (3 the lenses A are connected by a support comprising a bridging portion 1 and lens attaching devices or mounts 2 connected to the bridging portion. This connection, .in this instance, embodies a seat 3 in the form of a box entirely closed except on its ends. The box preferably has its greatest dimension transverse to the length of the mounting and is adapted to receive through either end thereof an attaching arm 4t carried by the lens attaching devices 2. The arm preferably lies with its greatest dimension transverse to the length of the mounting and has its inner end in spaced relation to the edge bearing portion 2 of the lens attaching device, being supported from the latter at one end by a supporting member which preferably is of greater thickness than the arm. Owing to the greater thickness of the support the entire end of the box is closed and the connection of the arm with the box 3 will not be apparent, except by close inspection. The member 5 also lies above and below and on opposite vertical sides of the, arm to form stops to limit the movement of the arm into the box. end of securing the arm 4 within the box 3, the arm 4 may be provided with an opening (3 and the box has its opposite horizontal walls provided with openings 7. These openings receive a fastener 8 which has a screw threaded engagement with the lower opening 7 and the opening 6 and is provided with a shoulder 9 which cooperates with the upper wall of the box 3 and presses the latter against the arm 6. The openings (3 and 7 are preferably located midway between the ends of the arm and ends of the box so that it is immaterial into which end of the box the arm is introduced, but it is preferred to locate the opening 6 in the arm to one side of the median plane of the lenses carried by the lens attaching devices. \Vith this arrangement when the arm is introduced into one end of the box the lens will be offset to the rear of the end of the bridging portion, whereas when the arm is introduced into the other end of the box the lens will be set forwardly of the end of the bridging portion. The supporting portion 5 connecting the arm 4 with the attaching To the devices 2 may be made of pliable material and permit a slight adjustment of the arm 4 transversely of the lenses so that the inset and the outset of the lenses may be varied. The nose 'uards preferably turn about axes coincident with the longitudinal axes of the fasteners 8 and to this end the fasteners are provided with bearing portions 10 on which the guards turn, the bearin portions in this instance projecting from the boxes above the su ort and having heads 11 at their upper ends to cooperate with the upper surfaces of the guards and hold the latter in firm engagement with the upper surfaces of the boxes 3. Each nose guard preferably comprises a lever 12 having the bearing portion thereof between its ends, the forward end bent vertically or downwardly at 13 and extended outwardly at 14 to provide a finger piece, and its rearward end carrying the nose bearing member 15 embodying upper and lower nose engaging pads. The guards are positioned by any suitable springs, but in the present instance a volute coil 16 is arranged in rear of the support and is formed integrally with the rear end of a guard, an arm 17 being extended forwardly from the outer end of the coil twisted at 18 to present but fiat faces horizontally at its forward end where it has sliding engagement with the hook or projection'19 depending from the under side of the box 3. In another embodiment of the invention, illustrated in Figs. 7 to 9, inclusive, the boxes 3* are carried by and on the inner side of the lens attaching devices 2, while the arms 4? are carried by the bridging portion 1, the arms being supported from their inner sides by connecting portions 5 instead of at their ends. It is desirable to cut away a portion of the inner wall of each box at 20 so that the opening 6 of the arm may be made to aline with the openings 7 a of the box for otherwise the ends of the bridging portion would be thrown too far in the rear of the lenses. In this instance the part of the connecting means on the lens attaching devices has its opening in the median plane of the lenses and it is therefore impossible to inset or outset the lenses. The connecting portion 5 also interferes with this action, and when this type of connection is combined with a guard spring operating on the principle described in Figs. 1 to 6, the projection 19, if the box 3 were turned to lnset or outset the lenses, would be thrown above the support, and this also is a reason for not providing for shifting the lenses in this embodiment. 1

Instead of providing a seat in the form of the closed box, I may construct the same as shown in Figs. 10 and 11, in which the seat 3 is horizontally arranged with its greatest dimension transverse of the length of the mounting and on the lens attaching device easaee 1 1 1i 2; and the arm 4* is constructed if desirable; in the manner shown in Fig. 9 and is en'- gaged directly by a shoulder 9 on the fas tener 8 The fastener may be extended above the shoulder to provide a bearing 10 and also act as a supportfor a coil spring which lies between a head 11 on the fastener and the upper surface of the guard lever 12 that turns on the bearing 10, one end of the spring engaging the lever at 21 and the other end cooperating with the lens attaching device at 22.

If it is desired to remove the mounting from the nose or place it upon the same, it is only necessary to press the operating portions or finger pieces 14: toward each other when the nose engaging portions 15 will be separated. After the desired position of the mounting has been reached the finger pieces 14 are released permitting the nose engaging members to move toward each other under the action of the springs. To remove the guards and the springs it is merely necessary to unscrew the fasteners and this action also permits the lens attaching devices to be separated from the bridging portion.

An eyeglass mounting constructed in accordance with this invention may be con structed with a very short pupillary distance as the greatest dimensions of the seats and the attaching arms between the lens attaching devices and the bridging portion lie transverse of the length of the mounting. A single screw serves as a pivot pin and as a fastener for connecting the bridging portion to a lens attaching device, and the lenses may be set inwardly or outwardly to correspond to the condition of the eyes of the wearer. This construction enables the Optician to carry a fewer number of eye glasses in stock as one mounting may be changed to agree with the facial characteristics of a great number of persons. When a lens attaching device breaks it is not necessary to send the whole mounting to the factory for repair as the optician may replace the same by another. The connections between the bridging portion and the lens attaching devices are strong and at the same time they do not render the mounting conspicuous by increasing the size of the same to any material degree.
